Schizophrenia is often associated with cognitive deficits, particularly wit
hin the domains of memory and language. Specific cognitive deficits have re
cently been linked to psychotic phenomena, including verbal hallucinations
and disorganized speech. Impairments of working and semantic memory are pri
marily due to dysfunction of the frontal cortex, temporal cortex, and hippo
campus. Cognitive skills in schizophrenia predict social functioning and ma
y serve as outcome measures in the development of effective treatment strat
egies.
